I would not re-pot right now, Lisa. The plant is going to have a tough time surviving and you don't want to stress it.
I generally grow all my "standard-size" Phal. in clay (unglazed, orchid pots) simply because Phal. gets top-heavy. I just go ahead and grow them in clay so I don't have to worry about them tipping over. But again, those plants you see are old ones (sold, long ago) and I really don't like to grow standard Phal. any longer. If my compact growers are not mounted, they are growing in mesh-pots, maximizing air-flow to their roots.
